%prog assumes that the user has a directory called ~/m5/<version> where
the source tree resides, and a directory called ~/build, where %prog
will create ~/build/<version> if it does not exist and build the resulting
simulators there.
If ~/build is set up in such a way that it points to a local disk on
each host, compiles will be very efficient. For example:
~/build -> /z/<username>/.build (Assuming that /z is a local disk and
not NFS mounted, whereas your home directory is NFS mounted).
